Description

 Multifunctional nail gun

Technical field

The invention relates to a hand tool, in particular to a multifunctional nail gun.

Background technique

The PCT patent "STAPLERWITHADAPTER" (Announcement No. WO2005/102613A1) discloses a nail gun suitable for four different sizes of nails, which can be applied to a T-shaped nail, a U-shaped nail, a dowel or a nail, and the sliding member is moved up and down. At the same time, the selective contact nail of the adjusting member is driven to achieve the purpose that different thick and thin nails can be applied. The disadvantage is that the design solution needs to first control the sliding member to slide up and down, and then manipulate the positioning member on the sliding member to achieve positioning, so that the nail gun needs two manipulations to achieve the positioning effect, and the user is inconvenient to operate. At the same time, the design scheme has the problem that the structure is too complicated, the positioning structure of the sliding member is too complicated, and the production cost of processing and assembly is high.

The Chinese patent "nail gun for a variety of nails" (publication number 101439509B) discloses a nail gun which can be applied to various kinds of nails, and can quickly adjust the distance between the adjusting piece and the nail, so that the nails of different thicknesses The needle is secured within the staple cartridge. The disadvantage is that in the design, only the structure of adjusting the distance between the adjusting member and the magazine is made, so that the nail gun can be applied to nails of different widths (or thicknesses); however, there is no solution for adjusting the striking force of the nailing device. Regardless of the thickness of the bound material, the nailing member must strike the nail with the same force. Once the bound material is thick, the nail can not penetrate all the bound materials, which will affect the nailing effect; meanwhile, the design In the solution, the runner structure is required, the processing and assembly precision requirements are high, and the production cost is also high.

There is a need for a new type of multi-purpose nail gun on the market that can be applied to nails of various specifications and widths, and can also adjust the striking force to better achieve the breakdown effect.
